Title: Calendering method and a calender that makes use of the method
Inventor: VILJANMAA MIKA
IPC: D21G1/02
Filed: 1998-03-26
Abstract: The invention concerns a calendering method, in which the paper or board web (W) is passed through the calender, in which calender the calendering nip (N) is formed between a heatable hard roll (11) and an endless, flexible and substantially non-compressible calendering belt (15) passed over said roll.  The heatable hard roll (11) is heated in order to plasticize the surface layer of the web (W) to be calendered placed at the side of the heatable roll, and the web (W) is brought into a preliminary contact with the heatable roll (11) before the calendering proper of the web (W). After the stage of preliminary contact (I), the press treatment proper is applied to the web (W) to be calendered in two stages. First a deformation is produced in the material web (W) in the press stage (II), after that the deformation that was produced in the press stage (II) is allowed to be reversed partially under control in a reversing stage (III), and a new deformation is produced in the material web (W), which was already once pressed and partly reversed, by pressing the web again in a finishing press stage (IV). After the finishing press stage (IV), the calendered web is supported by means of the calendering belt (15) over a certain distance before the web (W) is passed away from between the heatable hard roll (11) and the calendering belt (15).

Title: Apparatus for changing the direction of transport of oval cigarettes
Inventor: DAHLGRUEN ROLF
IPC: A24C5/32
Filed: 1999-10-06
Abstract: Plain oval cigarettes which issue from a maker in such orientation that the minor axes of their oval cross-sectional outlines extend vertically are advanced lengthwise in the spiral groove of a trough toward an outlet where the major axes of their oval cross--sectional outlines extend vertically. The thus reoriented oval cigarettes are attracted to the undersides of receptacles which are pivotably mounted on a rotary carrier and deliver the cigarettes, without any further changes in the orientation of the major and minor axes of their cross-sectional outlines, to successive peripheral flutes of a rotary drum-shaped conveyor which transports the cigarettes in such a way that the minor axes of their oval cross-sectional out-lines extend radially of the rotational axis of the drum-shaped conveyor. This ensures that the oval cigarettes are more reliably held in their flutes during advancement with the drum-shaped conveyor.

Abstract: An apparatus for increasing the flow of liquid in a conduit provides a barrier positioned in the conduit to prevent flow of liquid past the barrier in a lower region and defining a gap region above that lower region and adjacent the barrier. A duct having a first end for positioning within the lower region of the conduit upstream of the barrier and a second end for positioning in the gap region of the conduit to direct the flow of liquid through the duct from an area upstream of the barrier through the gap region to an area downstream of the barrier. An air pump communicates with the duct to force air into the first end of the duct under sufficient pressure to mix with water in the area of the first end of the duct and rise with the water through the duct and out the second end of the duct to the downstream side of the barrier. A plurality of apparatuses may be located at pre-determined intervals along the conduit.

Title: Chemically coated fasteners having improved penetration and withdrawal resistance
Inventor: LAT GERONIMO E
IPC: F16B19/00
Filed: 1999-12-14
Abstract: A polymer-coated metal fastener is provided which has both improved ease of drive into a substrate, and improved resistance to withdrawal from the substrate. The coated fastener is prepared by heating a metal fastener, or a portion of it, to about 400-2000°F and cooling in an aqueous medium containing an acrylic or modified acrylic polymer. The rapid cooling causes formation of a thin yet durable polymer coating on the fastener.

Title: Masking patterns to enhance apparent opacity of paper products
Inventor: WENDLER ROGER EDWARD JR
IPC: B41M3/00
Filed: 1999-12-24
Abstract: The present invention is directed to a paper product that is printed with a masking pattern. The masking pattern is such that it is not discernible on the paper product, yet is heavy enough to obscure objects which may appear behind the product to the eye of the consumer. In this manner, the consumer perceives the paper product to have a greater opacity than the product actually has, and thereby the consumer is not misled to assume the absorbency and/or strength of the paper product is less than is actually the case.
Patent CA-2293904-A1 (CA)
Inventor: PAGELS DONALD D JR
IPC: B25B5/04
Filed: 2000-01-04
Abstract: A clamp having a pneumatic cylinder with an actuating rod connected to one end of a drive arm which has its other end attached to a crankshaft which in turn has crankpins eccentrically mounted thereon to drive inner and outer clamp arms between retracted and advanced positions corresponding to open and closed positions of the clamp. The length of the drive arm, the extent to which the crankpins are offset from the crankshaft, the specific portion of a quadrant through which the crankpins are rotated, and the distance between the application of the force to the clamp arms and the axes about which the clamp arms pivot all provide a significant mechanical advantage and an extremely large clamping force from relatively low pressure compressed air supplied to the pneumatic cylinder.

Title: Transgenic plants with tocopherol methyltransferase
Inventor: SHINTANI DAVID K
IPC: C12N15/82
Filed: 1998-07-22
Abstract: Disclosed are gene sequences encoding .gamma.-tocopherol methyltransferases from photosynthetic organisms. The enzyme .gamma.-tocopherol methyltransferase catalyzes the methylation of .gamma.-tocopherol to yield .alpha.-tocopherol, the most bioactive species of tocopherol. .gamma.-Tocopherol methyltransferase is believed to be involved in regulating the relative amounts of the various tocopherols present in photosynthetic organisms. By introducing a genetic construct having a .gamma.-tocopherol methyltransferase coding sequence placed under the control of a plant promoter into a plant, transgenic plants can be made having altered .gamma.-tocopherol methyltransferase expression, to effect dramatic changes in the tocopherol profile of the plant. Transgenic plants can be made that have .alpha.-tocopherol as the predominant tocopherol in their seeds and oils.

Title: Channel code configurations for digital audio broadcasting systems and other types of communication systems
Inventor: SINHA DEEPEN
IPC: G10L19/005
Filed: 2000-12-06
Abstract: Improved channel code configurations for use in transmission of digital audio or other types of information in a digital communication system. The channel code may include an outer channel code, e.g., a cyclic redundancy code (CRC), and an inner channel code, e.g., a complementary punctured pair convolutional (CPPC) code. In accordance with the invention, multiple code words of the outer code are associated with a given packet of the digital information, in accordance with a particular outer code configuration, so as to provide partial error flagging for different portions of the given packet. An information encoder, e.g., a PAC encoder, interacts with an outer code encoder to determine a bit allocation for transmission of packets at a particular bit rate, based at least in part on the outer code configuration. The invention is particularly well-suited for use in the transmission of digital audio information in a hybrid in-band on-channel (HIBOC) digital audio broadcasting (DAB) system, but is also applicable to other types of information and other types of communication systems.
